Be it known thaty I, Tonia RICHARDJI-Iosl KiNs, a citizen of the United States of America, residing at Bartlesville, in fthe county of Washington and Stateot; Oklahonia, have invented certain new and useful Improvements in Dump Bailers, of which the following is a speciiication. j 'v This invention lrelates to an improvement in dumpbailers, of that type designed to deliver desired material to the bottoni of an oil or gaswell for plugging v,the same. The main feature or the present invention is the provision of means whereby'the inaterial being carried to the bottoni of the well is .protected against the oil or 'water in the welliduring transit, and is automatically deliveredwhen the bailer has l,reached the bottom of the well. f Y I The invention Y furtherQcoinprehends a. particular means whereby the bottom' of' the bailer proper is heldin closedposition dur-y ing transit and released through a trip mechanism, in turn `operated by contact with the bottom of the well, tlietripinechanism being adjustable in its control of the bailer bottom to cause they force oLtheV latter necessary ytoY release the bailer botto'rnito be variable 'at will. M i Y f The invention is illustrated in panying dra-wings, inv/'hichffA Fig. 1 is a view elevation otr-the iinf' Vproveddinnp bailer. Y t

A 4,5, `and '6, are respectively'enthe accom- 1 larged transverse sections onthe lines Y mit the contents of the bailer proper to reach lining' 4 ,torniedat' the lower kedge with a l 5-5, andf-Gfof Figjlff ,Y The improved diinipfbailefr' coinpri'se'saJ bailervsection Aproper fas V1, which, for@ the purposesof the present invention, may be an ordinary,v pipe section interiorly threaded at 4the upper endasatwherebv to permit the connection of additional sections for increasing the capacity 'f the bailer vproper and forlowering the latterfintoposition Y The bailer Section proper, whichv i'srCy'- lindricalinform, is 'extended as a halfy cy# lindrical portion 3, the "latter "being Jfully open on one sideand at' the bottom to perthebottom of the wellv through gravital ldclivery. Secured within the cylind'ricalportion lf'ot the bailer proper 'is an annular hinged "support v5,5 onwhich' isl hinge'd 'a f bottom or closure 46.V The Elining ineniben ,t-

'The bars If'near 'their lower ends'are provided withatransversev connecting pin KA12, "which'beyond the bars is mounted inthe free ends 'of' linlssl, g

which at their' Yopposite ends' are pivotally i 'supportedl on studs ldlsecured'fin the eXten- Y sion 301i' the bailer proper. Beyond the connecting pin 12, the bars? Yare extended in angularly related bar sections 15,' fwhich latter are of short length and connectedby Y* a Vtransverse locking pin 16. vThrough themed'ium of the connection de scribed,-V it is apparent that the supporting 'bars ,7 andlinks 13 formv a togglelever cion;-

nection, and that so long asy the connecting point of the v respective portions Yof the toggle connection, that `is,the connecting pin 12, is inwardly of a line between theV pin!) and the pivot studs 1l, the closure will re-y l main 'in' closed position.

A tri bar17 is slid p tension 3, being heldrbetween abutments 18,

on which are secured bridge bars"20 ,"thus bly niountedirn'the enr Y l providing a channel in vwhich the trip bar n is slidably held. "This tripbarisforined at ritslower end Ywith VVaflateral or enlarged depending terminalffvQSl adapted whenthe parts Va r e'infset position toengage 'the lock. s

ing pin 16 vand prevent'r'elative Voutward vinovernentV of' the connecting pin r12'. The locking pin 16 may, if desired, be'squa'red or formed with an angular surface to permit` accurate holdingcooperation of the latch therewith. minediatelyV below theL latch,

the vtrip bar is-f-ormed'with an @outwardly j' andy downwardly curved` portionlQll, V'and immediately beneath said portion with an inwardly curved portion Q5. The outwardly curved portion serves as an operating tace7 which, in the upward movement of the trip bar, serves to laterally displace the connecting pin 12 by engaging the locking pin 167 the movement continuing until the connecting pin 1Q is carried beyond the center when the parts pivot about the studs 14, the closure opens, and the connecting pin 12 iinally seats itselt' in the reduced portion 25.

rThe device is shown in operative or set position in Fig. 2, from which it will be noted that the latch 22 is in cooperation with the locking pin 16 and hence the release of the closure cannot be ellected. in this position, the enlarged end 31 ot the trip bar 17 extends below the extension so that as the bailer is lowered into the well, the projecting end ot the trip will be engaged by the bottom ot the well and the trip bar moved upwardly, with the eiicct to release the closure in the manner described and permit the gravital discharge of its contents.

It for any reason the material at the bottom of the well should be ot such sott consistencj7 as to permit the projecting end ot the trip to pass thereinto without operating the trip, the invention contemplates the ot a plate 26, which is adapted tor pivotal connection at 27 with the trip bar so as to be turned up at right angles thereto, and when in such position to engage with the trip bar to prevent further upward movement. A broad surface is thus presented which on contacting with even sott material will compel movement of the trip bar. The wall of the extension 3 is provided at diametrically opposite points with studs 28, adapted to engage the trip plate 26 when the latter has been moved a sufficient distance to cause the trip bar to etliect the release 'of the parts, the trip plate being thus swung down into inoperative position to permit a free flow olf the material to the bottom of the well.

It is of course apparent that the more nearly the connecting pin 1Q. is arranged in line with the pins 9 and 14, the easier the release may be eiiected, and to control the degree of force required to effect the release, adjusting pins 29 are mounted in threaded openings 30 in the wall of the eX- tension 3,.these adjusting pins 30 underlying the ends of the links 13 which engage the connecting pin 12. Through obvious adjustment of these pins 29, the connecting pin 12 may be spaced the desired distance from the wall of the extension 8, thereby permitting a greater or less movement of the connecting pin to break the joint. rlhus the trip bar may be made more or less sensitive in its action in breaking the joint and in actual delivery of the material controlled in accordance with the bottom conditions in the well.

As will be plain from Figs. 3, 4, and 5, the extension 3 is substantially semi-cylindrical and the operating parts are housed within such section, thereby providing an opening the full length oi the section through which the material delivered on the trip ot the closure will find its way to the bottom oit the well. It is further apparent that as the closure is tripped7 the locking parts described move tirst outwardly and then downwardly and inwardly, and that during this movement the closure proper is detlccting the material away -from such operating parts. Thus the material may be delivered intact to the bottom ot the well without interference from the operating parts.

What I claim is:

1. A dump bailer having a pivotal closure, a toggle lever support Jfor said closure, and a trip bar wholly free ot connection with said support and slidably movable for operating said support to break the joint.

5. A dump bailer having a movable bottom, supporting bars connected therewith, a connecting pin uniting` said bars near their lower ends, links pivotally connected to the bailer and to said connecting pin, said bars having angular extensions beyond the connecting pin, a locking pin connecting said angular extensions, a trip bar slidable in the bailer under contact with the well bottom, said trip bar being formed in part to engage the locking pin and detlect the connecting pin to break the joint.
